RE: OWA configurations

["Justin Dearing" <justind () invision net>]

This form of authentication is a Microsoft proprietary extension to http
that apparently uses some kind of challenge response it was called NTML
but in IIS 6 was rebranded Integrated Windows Authentication.

The previous technote provides some information. It does not go into
protocol implementation details but will give you a bit more info to
know what to ask google. 

As to how to brute force test it, I would recommend getting a bute
forcer that supports that protocol.

Subject: OWA configurations

In doing pen tests against various configurations of OWA, I have seen
two major flavors.  One, you receive the standard authentication request
for a username and password.  In those cases if you have a specific
domain you can prepend it to the domain name.  Other times you see the
request for a username, password and domain name as three separate
inputs.  In the second case can I prepend the domain name to the login
name, or am I required to enter all 3 pieces of information separately?

 
Am I correct in assuming that the choice of which form of authentication
you receive is set by the administrator?  If I have to enter all 3
pieces of information separately, does anyone know of a tool to do this?
Brutus/Hydra....tried both and neither has the option of specifying the
domain name as part of the brute force attempt.
